摘要
A recirculating-ball style gearbox for a vehicle steering system is provided. The gearbox has a rack with rack-teeth that are capable of providing variable ratio steering, where the rack-teeth are in mesh with the involute-teeth of a tapered sector gear. The involute-teeth of the sector gear have arrays of helical meshing lines extending across the meshing surfaces of the teeth, wherein the array of helical meshing lines have leads that decrease in length moving radially outward across the meshing surfaces.
